The Opportunity

We are searching for the right strong frontend engineer who will help us achieve our vision of helping millions of real local businesses succeed - someone who treats product quality as seriously as our customers treat their craft.

We are searching for the right high-judgment Senior Frontend Engineer (React) to raise the bar on frontend quality and deliver powerful AI-powered workflows in a simple, reliable, intuitive way.

You will take data-heavy, form-heavy, workflow-driven systems and make them simple and dependable for non-technical business owners at scale. Today, our customers depend on Hearth to run their businesses. When our technology works, contractors win more jobs. The frontend is where all of that comes together. You will take ownership of that customer experience and make it feel effortless.

What You'll Do:

• Lead management workflows - displaying, filtering, and acting on high volumes of inbound data from calls, texts, and web forms
• AI messaging interfaces - building the UI layer on top of our AI communication engine, where contractors review, customize, and send AI-generated messages
• Quoting and invoicing tools - complex form flows with validation, calculations, and edge cases that matter (wrong number format, missing fields, partial data)
• Integrations UI - connecting with third-party services like Twilio, payment processors, and CRMs, and surfacing that data cleanly
• Automation configuration - letting non-technical users set up AI-powered workflows without breaking things

What We're Looking For:

• React depth. 4-8 years building production SaaS applications with modern React. Hooks, async state management, complex form logic. You've built real features for real users and dealt with the messy parts - validation, permissions, error states, slow connections.
• API fluency. You're comfortable integrating with REST APIs, handling async errors gracefully, and building UI that degrades well when the backend doesn't cooperate.
• Product instinct. You think about the person using what you build. When a design is ambiguous, you ask questions instead of guessing. When a requirement doesn't make sense, you push back. You've built software for non-technical users and understand that simplicity is harder than complexity.
• Self-testing discipline. You try your own features before you ship them. You think about what happens when the input is empty, malformed, or unexpected. Bugs that a user would hit on first use don't make it past you.
• Communication. You can explain a technical trade-off to a non-technical teammate in a few clear sentences. You're comfortable working directly with backend engineers, customer success, and sales.
• Startup velocity. You've worked somewhere that ships fast and iterates. You're energized by that, not stressed by it.

Ideal Qualifications:

• Experience with messaging or notification systems (Twilio, real-time channels)
• CRM or lead management product background
• Experience building for SMB or blue-collar customer segments
• History of improving inherited frontend codebases

What We're Not Looking For:

• You lack pride in your work product and craft
• You rely heavily on QA to catch workflow bugs
• You measure success through completing tickets rather than delivering customer value
• You need heavy management or hand-holding
• You've only worked in large companies with narrow ownership of what hits the market
• You treat bugs as "edge cases" instead of failures to study
• You're looking for a "chill" job rather than an opportunity to do your life's work and build something truly impactful
• You're uncomfortable speaking with customers or working across teams

Why This Role:

• Real impact on real people. Our customers are business owners building real things. Over 50% go out of business without software like Hearth. When you ship a feature that works, a contractor in Phoenix closes a job they would have missed, and a Roofer in Texas stops losing 40% of inbound calls because he's on a job site, and a Fence pro in Delaware gets to come home for dinner with his family. The feedback loop between your code and someone's livelihood is short and tangible.
• A real business with serious traction and massive upside. Hearth is growing, profitable, and already has 15,000+ customers. This isn't a proof of concept - this is an opportunity to build the most ambitious version of a technology that powers a trillion dollar market. You would be building the customer experiences that power that transformation - early enough for meaningful equity and late enough for strong foundations.
• Elevate the Frontend Culture. Our customers are tradespeople who take pride in their work. We expect the same pride in our builders. We optimize for Craft, ownership, curiosity, high-agency, and the hunger to build something that actually matters in the world.
